Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed. May 28, 1897, Serial No. 638,545. Renewed February 6, 1907. Serial No. 356,097.

To all whom-it may concern:

Be it known that I, HARRY WIARD, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Plows, of which the following, taken in connection with the accompanying drawing, is a full, clear, and exact description.

My invention relates to plows, and has for its object the production of a high grade steel plow, which is particularly efficient in use, and is of such construction that the cutting edge of its mold-board and the lower edge of its land-side may be readily renewed; and, to this end, the invention consists essentially in the combination, construction and ar-' rangement of the component parts of a plow, all as hereinafter fully described and pointed out in the claims.

In describing this invention, reference is had to the accom anying drawing, forming a part of this speci' 'cation, in which like letters indicate corresponding parts in all the views.

Figures 1 and 2 are, respectively, top plan and side elevation of my plow. Figs. 3, 4,

j 5, 6 and 7 are sectional views, partly in elevation, taken, respectively, on lines 33 and 7-7, Fig. 1, and 4-4, 55 and 66, Fig. ,3. Figs. 8 and 9 are isometric views of the detached rear brace or spreader-bar and one of an isometric view of the detached shin-piece for the mold-board of my plow. Fig. 11 is an isometric view of the detached shoe for the land-side of said low.

The mold-boards and land-sides of high grade steel plows are each generally formed of front, middle or inner, and rear layers of steel, the front and rear layers being composed of hard steel, and the middle or inner The hard steel facilitates the scouring of the mold-boards and landsides, and their easy passage through the soil, and the soft steel affords the necessary strength. In the practical use of these plows,

1 as heretofore constructed, the cutting edges of the mold-boards and the lower edges of the land-sides wear with undue rapidity, and, when Worn, detract materially from the efficiency of the plow and can be repaired only with the utmost difficulty, and then not without deterioration of the mold-boards and land-sides. In order to prevent undue wear of the cutting edges of the mold-boards of plows of this character, many manufacturers weld wearing pieces upon the front faces of the mold-boards at their cutting edges, thus forming what are known to the trade, as mold-boards with double shins. The welding of these wearing pieces to the mold-boards, necessitates considerable heating of the mold-boards which injures their wearing surfaces, and also reduces the strength of the soft steel forming the middle or inner layers of said mold-boards. Moreover, when the double or reinforced shinpieces of mold-boards of this construction is returned to its user without re-hardening its mold-board, since shops of this character are usually unprovided with suitable means for re-hardening the mold-boards of steel plows.

My invention therefore has for its object the production of a high grade steel plow of such construction that the cutting edge of its mold-board and the lower edge of its landside may be readily renewed at will for maintaining the desired efficiency of the plow.

The mold-board of a plow embodying my invention consists of a main body A and a detachable shin-piece a, and the land-side of said plow consists of a main body B and a detachable shoe 6. The main bodies A B of the mold-board and land-side of my plow are composed of front and rear layers a a 1) b of hard steel, and middle or inner layers a b of soft steel. The middle or inner layer 6 of the main body B of the land-side extends to the lower edge of said main body, and, consequently, the central portion of said lower edge is formed of less hardness than the outer face of the land-side. The mold-board and land-side of my plow are secured to suitable supports, here illustrated as a frog 0, front and rear braces or spreader-bars c 0 and a plow-standard D. The frog 0 is usually provided with a front arm 0 and a supporting bar or arm 0 extending from front to rear of the plow. The front arm Figs. 3 and 5, is secured by'suitable fastening means as bolts .0 c, to the plow-point E and the main body A of the mold-board, and the supporting 5 arm 0 is secured by suitable fastening means, as bolts 0 to the main body B of the landside and is arranged with its lower edge in a plane substantially coincident with the plane of the lower edge of said body B.

10 The front brace or spreader-bar c is of any desirable form, size and construction and is suitably secured to the mold-board and the land-side of my improved plow. The rear brace or spreader-bar 0 preferably consists of a rod or bar having one end fixed to the main body B of the land-side and its opposite end provided with an engaging face a which is usually serrated and is adjustable lengthwise of a serrated engaging face provided upon an ear (1, projecting laterally from the inner face of the main body A of the moldboard. The end of the brace or spreaderbar 0 provided with the engaging face 0 is generally held in its adjusted position by a suitable bolt or other fastening means 0 passed through lengthwise slots 6 d formed in said end of the brace or s n'eader-bar c and in the ear (I.

The brace or spreader-bar 0 when constructed and connected as described, is readily secured in'position and does not require careful and expensive fitting. The car 61 is usually provided upon a handlebracket d which is generally secured to the main body A of the mold-board by a pivot (1 arranged in close proximity to said ear. The bracket (1 is additionally secured to the main body A by a bolt or fastening member-d which is fixed to said main body and is passed 40 through a substantially transverse slot d in the handle bracket (Z By securing the handle-bracket (P, as shown and described, the outer end of the handle D supported by said bracket may be suitably adjusted vertically.

The shin-piece a is usually arranged with the front face or wearing surface of its outer side portion alined with the front face of the adjacent part of the main body A, of the 0 mold-board. The inner side portion of said shin-piece is lapped upon the rear face of said adjacent part of the main body A of the V mold-board, and is preferably formed with a lengthwise groove or cutout a in its front face, which is arranged at one side of the wearing surface of the shin-piece and receives said adjacent part of the main body A. The fastening means for securing the shiniece a in position, usually consists of the bolt 0 previously mentioned, and a number of additional bolts 0 passed through the inner side portion of said shin-piece and the adj acent part of the main body A of the moldboard. One of the bolts 0 is engaged with a handle-bracket d secured to the standard D and to one of the handles ,D of my plow. As

a portion of the shin-piece a is lapped upon the main body A of the mold-board, the front arm 0 of the frog 0 arranged at the rear of said portion of the main body A, is formed l with a groove or cutout c in its front face for receiving the adjacent portion of the shinpiece. The described means for securing the shin-piece a in position is particularly practical and effective, but it will be understood that said shin-piece may be otherwise secured in position, if desired.

I preferably form the shin-piece a of front and rear layers or pieces a a of metal fiXed together in any desirable manner, as by weldg0 ing. The front layer or piece a is of less width than the rear layer or piece a, is alined with the front layer a of the main body of the mold-board, and is of substantially the, same hardness as said front layer a. The 35 rear layer or piece a of the shin-piece a is formed of comparatively soft metal, in order that said shin-piece may be firmly and positively clamped in position without liability of breakage.

A mold-board of the construction illustrated and described is particularly desirable, since its shin-piece is firmly held in position and is readily removed and replaced by a new shin-piece without any liability of deterioration of the mold-board.

The shoe I) for the land-side of my plow preferably consists of angularly arranged continuous ribs 7) disposed respectively 'in substantially horizontal and upright planes. The horizontal rib Z2 is arranged beneath the lower edges of the main body B of the land side and the supporting bar or arm a of the frog 0, and is formed of substantially uniform width from front to rear, in order that the shoes of right and left-hand plows and of different sizes of my plows may be interchangeable with each other without variation in the pitch of the lower edge of the landside. The rib b is engaged with the inner side of the supporting bar or arm 0 of the frog 0 and is held in position by the fastening means 0 for securing said bar or arm to the main body B of the land-side. The shoes I) are preferably formed of rolled wrought metal, since they may bethus manufactured economically and with great uniformity in the thickness of their lower ribs 6 The construction and operation of my plow will now be readily understood upon reference to the foregoing description and the accompanying drawing, and it will be particularly noted that the detail construction and arrangement of its component parts maybe more or less varied without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a plow, the combination of a point, 13

the main body of a mold-board, a shin-piece for the mold-board, said shin-piece being lapped upon the adjacent part of the main body of the mold-board, and. a frog secured to the point, the main body of the moldboard and to the shin-piece and having a groove or cutout in its front face for receiving the adjacent part of the shin-piece, substantially as and for the purpose specified.

2. The combination with the standard and frog of a plow; of the main body of a moldboard, a detachable shin-piece for the moldboard, and means for securing the main body of the mold-board and the detachable shinpiece to said standard and frog, substantially as and for the purpose set forth.
